This file includes 7 bluish light burn footage clips, all FullHD 1920×1080 quicktime photo jpeg.
Files do not include an alpha channel, so you can overlay the clips over your footage with an additive blending mode. (Add, screen, lighten, etc.) “Add” seems to be the best method. If your compositing or editing software does not support blending modes, check your plugins. (Genarts Sapphire “Math_ops” & other plugins, supports compositing with blending modes).
